CVE-2026-40026
MEDIUMSleuth Kit ISO9660 SUSP Extension Reference Out-of-Bounds Read
Title source: cnaDescription
The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the ISO9660 filesystem parser where the parse_susp() function trusts len_id, len_des, and len_src fields from the disk image to memcpy data into a stack buffer without verifying that the source data falls within the parsed SUSP block. An attacker can craft a malicious ISO image that causes reads past the end of the SUSP data buffer, and a zero-length SUSP entry can trigger an infinite parsing loop.
